Overview:
The purpose of data analysis is twofold: Statistical Parametric Mapping (SPM) levels 1 and 2. Level 1 consists of preprocessing data as well as adding beta values to the hemodynamic response functions (hrf) of individual participants, whilst level 2 is where the hrf beta values from multiple participants are compared.
Opening a file:
To begin level one, open “nirsLAB” from the desktop icon. After clicking a matlab window will open and start the program.
With nirsLAB running, click “load data” as show in the image.
Navigate to the subject data by clicking [OS Disk (C:)], then opening the [nirX folder] and selecting [data folder].
Once in the data folder, folders will be named by dates. Pick the date when the trial was run and chose the appropriate participant file and select the file ending in “config.txt”. This file should be located at the bottom of the subject’s folder and may have a name similar to the following: “NIRS-2016-05-27_002_config.txt.”. (Image configure text image)
Once the config.txt file has been selected, the file will load and a message will be displayed at the bottom of the screen within the "Running Status Box" indicating that the file has loaded.
